Cleaning the water inlet of the dishwasher – An overview

Dishes, pots and cutlery are still dirty or calcified after cleaning in the dishwasher? If so, the dishwasher water inlet may be dirty and in need of cleaning. Fortunately, with the right preparation, the water inlet can be cleaned effectively so that the dishwasher can be used again afterwards.

Create access to the water inlet

One of the most important steps before you can clean the water inlet for the dishwasher is to access it. Since dishwashers are usually integrated into the kitchen, the hose is not always visible. This is not the case with freestanding appliances. With these, the water inlet is immediately visible and just as easy to reach. In contrast, with permanently integrated dishwashers, you first have to get to the inlet.

The machine should be switched off for this. Remove existing baseboards and open the fasteners for the dishwasher, which are located on the side or top of the countertop, depending on the kitchen. Now you can pull the dishwasher forward up to 20 cm.

Cleaning the inlet hose

Cleaning the water inlet of your dishwasher is an essential maintenance task to ensure optimal performance and prevent issues like clogs and poor washing results. Here’s an overview of how to clean the water inlet of your dishwasher:

1. Preparation:
   • Turn off the dishwasher: Before starting any maintenance, make sure the dishwasher is turned off and unplugged from the power source to ensure your safety.
   • Access the water inlet: The water inlet is usually located at the back of the dishwasher, where the water supply hose connects to the appliance. You may need to pull the dishwasher out slightly to access it.
2. Remove the water supply hose:
   • Locate the water supply hose: The water supply hose is typically connected to the water inlet at the back of the dishwasher and the main water supply valve.
   • Turn off the water supply: Locate the main water supply valve and turn it off to prevent water from flowing into the dishwasher.
   • Disconnect the water supply hose: Use pliers or an adjustable wrench to loosen the hose connection at both ends (dishwasher and main water supply valve). Be prepared for a small amount of water to drain out when disconnecting the hose.
3. Clean the water inlet:
   • Inspect the water inlet: Check the water inlet for any visible debris, such as food particles or mineral buildup. Use a flashlight if needed.
   • Remove debris: Use a small brush, like an old toothbrush, to gently scrub away any dirt or debris from the water inlet. Pay attention to the small holes or screens in the inlet and ensure they are clear.
   • Vinegar solution: Mix equal parts of white vinegar and warm water in a bowl or container. Dip a soft cloth or sponge into the vinegar solution and wipe the water inlet to remove any stubborn residue or mineral deposits. Vinegar helps dissolve mineral buildup effectively.
4. Reassemble and test:
   • Reconnect the water supply hose: Once the water inlet is clean, reconnect the water supply hose to both the dishwasher and the main water supply valve. Tighten the connections securely.
   • Turn on the water supply: Open the main water supply valve to allow water to flow into the dishwasher.
   • Plug in and turn on the dishwasher: Plug the dishwasher back into the power source and turn it on. Run a test cycle to ensure the water inlet is working correctly and water is flowing without any leaks.

It’s generally recommended to clean the water inlet of your dishwasher every few months or as needed, depending on the quality of your water supply and the frequency of use. Regular maintenance helps prolong the lifespan of your dishwasher and ensures it continues to provide efficient cleaning results.

Change hose

On rare occasions, the water supply hose may be badly damaged or kinked to the point of rupture. In this case, it’s important to replace it or you’ll have a leak and possibly water damage. Fortunately, the hoses can be easily replaced after disconnection.
